.cEirnn'rI-'rros Bonn non snronrine ovnu'nnzenn vWinn/s AND LIKE Indiana,- have invented. new and usefuilmprovements in Cementitious Poles 'for Supporting OverheadiWiresor the Like, ofwhich the following is'acomplete and -accurate specica'tion and exposition, being such as y will enable others skilled in the art-towhiclifthe invention pertains to make and use 'the same with abgelute exactitude.

This my present invention consists ina :petrous or other analogous purposes;

The object oi my invention, broadlyspeaking'is the'production of. a Vsolidified cenientitions'pele for` supporting Wires,' cables, let cetera',...yv'hilch ,will 'be `strong and "durable in construction, havinggreat tensile-strength,uwhiehiwill. be economically etlciennbeing impermeable' to moisture, 'and which will not deteriorate by long usage or exposure to the weather.

More speciiallymy object is to produce a polelike structure proportionable tothe amplitude of its various` requirements, comprising a petrousfor ston'e'likeV body interiorlyreinforcedwith metal whereby'- it may have a certain amount of flexibility without danger oi breaking, vand whereby the danger of its breaking or 'crumbling is practically nite Another object is to provide a cement pole containing a maximum height with a I'n'ininiuin diaineter,

' which' is obtained by reason .of a predetermined amount of cementitious compo moldedabout a ske le` tonizedfabrication of metal, which-when completed: and'desiccated will present smooth superces and,l preferably, truncated corners. And, nally,l1 ny ob#- ject is'to provide apractically non-destructiblefand ,non-deteriorating pole which can be manufactured and soldat a comparatively low price,'having means whereby-cross-arms may be secured thereto, and having means wherebyitmay be scaled when it is vin a vertical' position.

f Other objects and particular advantages' will belv made apparent in the course o f thel ensuing 'specification.

lThe' preferred embodiment of-my invention, andl that which in'practijce has been'determned the most- 4 practical `i s 'v isualize d'in the accompanying'drawings,

coilpleted.pole; 3 is aplan view of the topof the' .-pole; Fig. 4 shows a vcross-section as taken on the line the liue ofFigrl. `Fig.'6 shows a modification oi v 'the partsshowniniligs. 2., 4e and 5. And 7 shows `another inodification,. or addition, which may. .be "employed vin the constructionfl' f Similar characters denote like parts throughout the vseveral.views of the drawings'. Y

v f In orderthat theconstruction and advantages of this invention may loe the more readily understood Iwill y .now take-up a .detail description, in which I will refer to the various parts and the construction as `brieyand -as eompactlyas Imay. l i

lThe pole proper, .and the predominant element com prising the entire construction thereof, is the'cementi# tions bodyI l which Vshould be formed tapering 'upwardly 4 frombase to apenA as indicated, and it may bel ofany preferred configuration in cross-section, but I 'prefer that it-beformed .with four faces identical with each other, each face converging upwards. I also prefer i that the polebe formed-with truncated corners, formfour additional faces which are also identicalwith each other and of same width throughout their' lengths, substantially asindicated in Fig. 1. The periphery oi the top of the pole so vformed describes a true octagon,

from which it converges abruptly to the center forming fa cone-like top, asis indicated in Figs. 1 and 3l The body so formed fis reinforced by, preferably, four rods or bars, indicated bythe'in-umerals 2 3, 4 and 5 which are square in cross-section. Said rods should be twisted separately forming each a spiral, as indicated in Fig. 1;

Said'rods I "prefer to positionnear the corners of the pole, .sarnebeing located substantially as indicated in Figs.l 4. and`5, and they should extend longitudinallyA of the' pole and from end.toendthere'oi In order to prevent said rods from pressing' outwardly out of aline-V ment with 'each other they shouldbe'encircled bya spiral wir-@L6 lextending 1in convolutinsjtherearound This wireclosely encircles the rods, vand'fjas 'stated,

. confines them against outward displacement during 'the molding Operation. l

The numerals =-7 8 and 9 denote outwardly extending threaded belts, their heads' being embeddedin the bedy 1, and their threaded portions protruding. i

Formed through the upper 'portion of the pole are.

.bolt-apertures 10 and 11, formedona linel w-ith said f above the bolt 7 through which passes thebolt 124. The

. numeral llde'signatesa crossfarm which is secured inits center tothejpolevby'saidbolt 12. Said vcross-arm is iurtherfseeured by the twobraces 14aud 15 whose over- `-1epp`ing inner ense ere seemed te the. peleby the een bolt 7, vand the outer diverging ends of said braces are Vsecured to the cross-arm by the'respective bolts 16 and v 17, shown inxFig. l. It is notably' apparent that curable by the bolts 8 and 9,

In order that the polemay be scaled I provide steps,

other cross-arrns may be secured to the pole by passing bolts, 4like the bolt 12, through the apertures 10 and l1,

and the braces for such additional cross-arms being seas for instance the steps 1 8, 19 andv 20, and 21,' 22 and v23, each having its threaded end embedded in the body` of the pole, as is shown by 'the step`18 in Fig. l.

The letter-A designates the ground-line, `it of` course being understood that the pole just described is to be securedin the ground'substantially as isindicated in Fig. 1.- i i.

.If found-advisable the rods `2, 3, 4and 5 may be fun` ther secured withrelation to each` other by inter-cross'4 wiring, as indicated in Fig. 7, which may be located at:

' h, as shown in l'i ig6, said rods being in every essental'particularlikje the rods 2, 3, 4, and 5, except in arrangement with relation'to the'body. l. Said eghtrods erspersedas desired.. l

In practice the pole may be constructed horizontally I' prefer lto arrang in pairs, although they vmay be in- `1 in molds or the like and after desiccating and solidifying it rnay be raised in the usual manner; or, probnldy the most preferable, it vInay be. built up und formed entirely in the position and at the point il. is intended to permanently occupy, .v

Fromthe above it is apparent that l accomplish the objects of my invention in a practical and mechanical manner, thereby7 providing a pole which will have all of the essential requisites.

:While I have herein 'shown and described the best mea'nsto me known at this time for the carrying out ol' the objects-oi my invention in a practical manner, I

'desire to have it distinctly understood that I do not restrict myself to the exact details of construction shown and described, but hold that any changes or variations therein las would suggest themselves tothe ordinary mechanic' would clearly fall within theliinits and scope of my invention.

L. AHaving now ullyshovvn and described my invon tion, what I claim anddesire to secure by Letters Pat ent ofthe United States, is`

A reinforced cement pole consisting of an elongated coment body inclosing :1 plurality of longitudinal rods -or thelike remote from each other and disposedl about the longitudinal axis of the body, :1nd a wire or the like dis posed in :n.contiuuous spiral about and closely encircling said rods substantially from end to end .of the body.

Y In testimony whereof l have hereunto subscribed my name in the presence of two subscribing witnesses,
